Description

Technical Field

[0001] The utility model relates to the technical field of vibration test benches, and in particular to a vertical inertial vibration test bench. Background Technique

[0002] The purpose of vibration testing is to verify that the designed product can withstand external or self-generated vibrations without being damaged and can perform its functions to reach the predetermined service life.

[0003] The existing vibration test benches include a horizontal test bench and a vertical test bench. Taking the vertical test bench as an example, the test bench includes a vibration table and an extension table installed on the top of the vibration table. During the test, the product needs to be placed on the extension table, and the vibration table drives the extension table to vibrate up and down at a high frequency, so as to achieve the purpose of product performance testing.

[0004] Under normal circumstances, as Figure 1 shown, the vibration table 1 and the extension table 2 are connected by a plurality of bolt assemblies 10. During installation, it is necessary to rotate the bolts from the top wall of the extension table 2 to fix the bolts on the vibration table 1, so as to realize the fixation of the vibration table 1 and the extension table 2. Since the test bench is relatively high, it is inconvenient for the installer to fix the vibration table 1 and the extension table 2 using the bolt assemblies 10.

[0005] Therefore, how to design a vertical inertial vibration test bench that is convenient for installing the extension table has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0006] In order to solve at least one technical problem mentioned in the background technique, the purpose of the utility model is to provide a vertical inertial vibration test bench to solve the problem that the extension table is inconvenient to install.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A vertical inertial vibration test bench includes a vibration table and an extension table installed on the top wall of the vibration table. One of the vibration table or the extension table is installed with a T-shaped connector, and the other is installed with a plug-in slot for the T-shaped connector to be inserted. A locking slot is communicated with the side wall of the plug-in slot. A locking plug board and a driving mechanism for driving the locking plug board to move are slidably connected in the locking slot. When the locking plug board is inserted into the T-shaped connector, the vibration table and the extension table are locked.

[0009] Further, the T-shaped connector is installed on the top wall of the vibration table, and the plug-in slot, the locking plug board and the driving mechanism are installed on the extension table.

[0010] Further, the T-shaped connecting member includes a longitudinal pillar fixedly installed on the top wall of the vibration table and extending vertically upward, and a limiting rod installed on the longitudinal pillar. The limiting rod is horizontally arranged and fixedly connected to the top of the longitudinal pillar. The locking plug is U-shaped. When the extension table is locked with the vibration table, the top wall of the limiting rod abuts against the top wall of the insertion slot, the longitudinal pillar is inserted into the opening of the locking plug, and the top wall of the locking plug abuts against the bottom wall of the limiting rod.

[0011] Further, the driving mechanism includes a threaded rod and a rotating table fixedly installed on the side wall of the extension table. The threaded rod is rotatably connected to the rotating table and extends into the locking slot. The threaded rod is threadedly connected to the locking plug, and the bottom wall and the top wall of the locking plug are respectively slidably connected to the bottom wall and the top wall of the locking slot.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: By installing a T-shaped connecting member on the vibration table and then providing an insertion slot on the extension table, when the extension table is installed, the T-shaped connecting member is inserted into the insertion slot, and then the driving mechanism is used to drive the locking plug to be inserted into the T-shaped connecting member, thereby realizing the locking of the extension table and the vibration table. This installation method does not require rotating the bolts from the top wall of the extension table, and the installation of the extension table can be achieved through the driving mechanism from the side of the extension table, making the installation of the extension table more convenient and reducing the installation difficulty of the extension table.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] This embodiment provides a vertical inertia vibration test bench, which mainly solves the problem that the test bench is relatively high and it is inconvenient to install the extension table and the vibration table.

[0023] As Figure 2 and Figure 3 shown, the test bench includes a vibration table 1 and an extension table 2 installed on the top wall of the vibration table 1. Among them, under normal circumstances, as Figure 1 shown, the vibration table 1 and the extension table 2 are connected by a plurality of bolt assemblies 10.

[0024] In order to ensure the stability of the test bench during operation, the extension table 2 is generally made of cast iron, and the weight of the extension table 2 is relatively large, which is inconvenient for the installation of the extension table 2; therefore, when installing the extension table 2, a crane is needed to lift the extension table 2, and then place the extension table 2 on the top of the vibration table 1 so that the extension table 2 is inserted into the stud of the vibration table 1. When the extension table 2 is placed stably, the bolt is inserted downward from the upper direction of the extension table 2 so that the bolt is in threaded fit with the stud, thereby completing the installation of the extension table 2.

[0025] During this process, since the tabletop position of the extension table 2 is relatively high and the bolt needs to be inserted downward from the top wall of the extension table 2, it is very inconvenient to fix the extension table 2, which affects the assembly of the extension table 2 and the vibration table 1.

[0026] In order to simplify the installation of the extension table 2, in this embodiment, as Figure 3 and Figure 4 shown, a vertically upward extending T-shaped connector 11 is fixedly provided on the top wall of the vibration table 1, and a plugging groove 211 that is recessed inward and for the T-shaped connector 11 to be inserted is provided on the bottom wall of the extension table 2. Among them, as Figure 4 and Figure 5 shown, a locking groove 212 communicated with the side wall of the plugging groove 211 is provided, and a locking mechanism that locks the T-shaped connector 11 in the plugging groove 211 is slidably connected in the locking groove 212.

[0027] Specifically, as Figure 3 and Figure 4As shown, the T-shaped connector 11 includes a longitudinal pillar 111 and a limiting rod 112. Among them, the longitudinal pillar 111 is fixedly installed on the top wall of the vibration table 1 and extends vertically upward. The limiting rod 112 is horizontally arranged and fixedly installed at the top end of the longitudinal pillar 111. Specifically, the middle positions of the longitudinal pillar 111 and the limiting rod 112 are fixedly connected; the longitudinal pillar 111 and the limiting rod 112 form a T-shaped structure.

[0028] As Figure 4 and Figure 7 shown, the locking mechanism includes a locking plug 3 and a driving mechanism for driving the locking plug 3 to slide in the locking groove 212. Among them, as Figure 7 shown, the locking plug 3 has a U-shaped structure. As Figure 4 and Figure 5 shown, when the T-shaped connector 11 is locked in the insertion groove 211, the top wall of the limiting rod 112 abuts against the top wall of the insertion groove 211. The locking plug 3 moves to the bottom of the limiting rod 112 under the action of the driving mechanism, and the opening of the U-shaped locking plug 3 allows the longitudinal pillar 111 to be inserted. The top wall of the locking plug 3 abuts against the bottom wall of the limiting rod 112.

[0029] Through the above settings, by inserting the locking plug 3 to the bottom of the limiting rod 112, the upward movement of the extension table 2 is restricted, thereby completing the fixation of the extension table 2 and the vibration table 1.

[0030] It should be noted here that when the locking plug 3 is inside the locking groove 212, the bottom wall and the top wall of the locking plug 3 respectively abut against the bottom wall and the top wall of the locking groove 212.

[0031] In order to realize the movement of the locking plug 3, in this embodiment, as Figure 5 , Figure 6 and Figure 7 shown, the driving mechanism includes a handle 41, a threaded rod 42 and a rotating table 43. Among them, the rotating table 43 is fixedly installed on the side wall of the extension table 2. The threaded rod 42 is rotatably connected to the rotating table 43 and is inserted into the locking groove 212. Among them, the threaded rod 42 is threadedly connected to the locking plug 3. The handle 41 is located outside the extension table 2 and is fixedly installed on the threaded rod 42.

[0032] Through the above settings, when holding the handle 41 by hand, the threaded rod 42 can be driven to rotate by driving the handle 41. Since the bottom wall and the top wall of the locking plug 3 abut against the bottom wall and the top wall of the locking groove 212, the rotation of the locking plug 3 can be restricted, and thus the locking plug 3 can be driven to move along the direction close to or away from the T-shaped connector 11.

[0033] As Figure 6 shown, during the installation process of the extension table 2, first use the handle 41 to move the locking plug 3 to Figure 6As shown in the position in [description], at this time, the locking plug 3 is completely located within the locking groove 212, leaving the position of the insertion slot 211 reserved to facilitate the insertion of the T-shaped connector 11 into the insertion slot 211. After the T-shaped connector 11 is inserted into the interior of the insertion slot 211, the driving mechanism is used to push the locking plug 3 to move towards the side of the T-shaped connector 11, so that the locking plug 3 is inserted to the bottom of the limiting rod 112, as Figure 5 shown, restricting the up and down movement of the T-shaped connector 11, and thus completing the connection between the extension table 2 and the vibration table 1.

[0034] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
